16 Claims.l (Cl. 164-115) This invention concerns punching machines, particularly of the type in which key controlled, or duplicate punching operations, skipping and cut-out of duplicating operations, -may be effected, and has for its general object the provision of certain improvements whereby the different functions previously `performed under manual selection or control, or by the use f specially formed elements, may be dispensed with and such functions may be performed under a new forni of control and elements and in accordance with the predetermined lmanner of operation of the machine.

Inthe tabulating card punching machine art, it is the common practice to provide a punching machine which, under control of` keys, is adapted to designate statistical data on tabulating cards, and in carrying out punching operations it is also necessary from time'to time to commonly duplicate on a series of cards the data represented on a so-called "master card. Machines for effecting such duplicating operations are also Well known and shown in many prior patents.

It is at times undesirable to effect duplicating punching operations for certain fields of the mastercard and such duplicating punching operations have heretofore, been prevented or cut out under control of the so-called cut-out mechanism.

It is also at times desirable to effect the skipping of one or more card columns of the card to be operated upon since such columns may have previously been punched and this may be efiected either under control of the repeated operation of a skip key or alternatively, by the provision of a so-called skip bar.

In machines disclosed in the prior art, the cut-out and skipping functions have been effected under control of metal bars which, upon an order, are formed at the factory so as to take care of certain requirements in punching cards. For each different type of punching operation' a different form of skip bar for effecting either cut-out or skipping operations was required. It is obvious that in order to take care of the varied requirements for punching cards a number of these expensive bars were required to be on hand, each formed differently so as to meet the different punching requirements.

It occasionally happened that, in order to take care of a certain requirement which came up unexpectedly and without advance notice, there was not at hand a skip or cut-out bar which would control the machine in the desired manner. Rather than hold up the procedure of punching cards in accordance with the desired requirement until a new bar was obtained, the punching machine had to be operated in an ineiiicient manner. In order to skip certain card columns it was necessary to repeatedly operate the skip key and,

correspondingly, for effecting the cut-out of the duplicating operations certain other expedients had to be utilized, and in each case the speed of operation of punching machine was greatly reduced, and its operation performed in a less eiiicient manner. The main object of vthe present invention is to provide an improved form of means, whereby the cut-out and the skipping operations, as well as other functions of the punching machine, may be predetermined solely by perforations in a control card inserted in the machine. Such relatively inexpensive control card is similar in form to the ordinary tabulating card and with the new' arrangement the punching machine itself is utilized to effect the periorating of the control card at any desired time'so as to cause the punching machine to carry out the different functions in accordance with some predetermined plan. rThe positioning of this control card in the punching machine will automatically condition certain controlling mechanisms so that the different functions of the punching machine may be effected automatically, and without attention of the operator.

A still further object, with respect tothe analyout mechanism whereby electrical controlling circuits may be made under control of the column read-out mechanism in accordance with the previous analysis of the control card. The above arrangement avoids the necessity of passing over the control card analyzing brushes which are operated step by step, and which would rapidly damage or tear the perforations in the control card as the latter was analyzed by the repeated analysis of the brushes passing over the card itself. 'v

More specifically, considering sub-combinations of the presentimprovements, it is one 0bject of the present invention to provide a skipping mechanism for a card carriage lwhich is initiated in operation under control of va perforation in a control card, and to terminate the skipping operation under control of a perforation in a succeeding card column of the same control card.

.The last-mentioned object is carried out by 56 types.

providing an electrical relay system which includes a magnet, the energization of whichele- Vates the usual holding pawl of the escapement mechanism permitting the card carriage to escape. In accordance with the succeeding perforation of the control card another relay is effective which blocks the movement of the card car.- riage and effectively locks it in the position to which it is skipped.

Certainother improvements incorporated in the relay system of the skipping mechanism are for the purpose of providing an efficient operation of the improved skipping mechanism, so that such operations may be -eiiiciently performed and exactly in accordance with the predetermined plan.

Another objectv of the present invention is to provide a novel electrical control system for the duplicating mechanism of the punching machine, and wherein the initiation .of the duplicating function may be performed under control of an initial perforation in the control card and may be terminated by a succeeding perforation in the same control card. By reversely arranging the perforation in the control card.the sequence of operation may be varied, and by the provision of this flexible relay system duplicating and cut-out of the duplicating operations may be effected in a predetermined sequence.

Still another object of the present invention is to provide means, which preferably actsupon the completion of the last function performedwith respect to the last card field, so that the parts utilized in this last funtcion are restored to normal thereby conditioning at this time all of the parts to normal,to enable the initial function which is performed on the first card field of the succeeding card to be performed in a more eicient manner. In the present form of machine a limited time is available for conditioning such parts to normal and for initiating the first function on the rst card field of the succeeding card, and it is preferable to condition all the parts operated to normal before the card carriage is positioned to the iirst card column position.

It is understood that while it is preferable and desirable to incorporate in a single machine all of the novel features shown herein, certain of the features may be used separately in a punching machine of the form shown herein, or even incorporated in punching machines of other The utilization of all of the novel features `provides a flexible machine which may be considered universal with respect to the different and predetermined requirements of punching systems.

In certain other requirements all of the features may not be required and such features may be used separately and isolated from the others.

It is, therefore, to be understood that the preferred embodiment of the invention shown herein is merely illustrative and should not be considered as restrictive.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principle of the invention and the best mode, which has been contemplated, of applying that principle.

ANALYzINo MECHANISM There will -now be described the construction of the analyzing mechanism which is adapted to analyze the control card designated l0 in Fig. 2. The present machine is adapted to perform four different functions with respect to a card and in order to select or determine the functions to be performed as the successive card fields are to be operated upon, the analyzing mechanism pre-analyzes the card I0 to thereby control such functions. Since four different functions are capable of being carried out by selection, a corresponding number of horizontal rows are appropriated, which at the intersecting selected vertical card columns receive perforations to initiate the operation of certain means so as to cause the machine to function in a certain way. The manner in which these different functions are carried out under control of the control card I0 will be further explained as the specification progresses.

The construction of the analyzing mechanism is best shown in Figs. 3, 4, 5 and `6 to which special reference should be made. In general, the analyzing mechanism comprises a lowersttiels ary contact unit and an upper movable analyzing unit. The assembled analyzing mechanism is carried by a plate Il (Figs. 3. and b) which is attached by screws l2 to the frame 9 (Fig. 5) of the punching machine. The plate l l is adapted to carry, in addition to the analyzing mechanism, certain other parts forming part of the present improvements.

The lower unit of the analyzing mechanism comprisesa base I3 of insulating material which is formed, as best shown in Figs. 3 and 4, at its ends with integral card guides i4 which are separated to an extent corresponding to the horizontal dimension of the control card l0, so that by the cooperation of the guides I4 with the shorter marginal edges of the control card the latter will be properly guided and located with respect to the analyzing elements. For the purpose of making desired adjustments ofv the card analyzing mechanism with a column selecting mechanism to be later described, the base, I3 is attached to the plate II by means of adjusting screws I5 (Figs. 3 and 5) -which pass through slots I6 in the base I3. The upper surface of the base I3 is recessed at each'slot I6, as designated by reference `numeral I1, so that the head of the screw I5 will project beneath the upper surface of the base I3, thereby preventing interference with the control card I0 when the latter is manually inserted in the analyzing mechanism.

As best shown in Fig. 4, there is embedded in the base I3 a plurality of contact bars I8, there being one bar for each card column except the rst card column, and for a reason which will be obvious as the construction is better understood. The left ends (Fig. 4) of the seriesl of contact bars I8 are flush with the corresponding edge of the base I3 so that, by a suitable column contact making mechanism, contact with the bars I8 may be successively made. It should also be mentioned that the base I3 carries av common current conducting bar I9, which is best shown in Figs. 4 and 5, and the bar I9 forms'part of the contact making unit which includes the contact bars I8.

In order to provide a stop for the control card when the latter is manually positioned in the analyzing mechanism, the base I3 carries a stop plate 2D (Fig. 4), preferably of insulating material, and the latter is engaged by one of the longer edges of the control card so as to suitably locate the latter in the analyzing unit. As best shown in Fig. 5 a card operated lever 2| is pivotally carried by a bracket attached to the base I3 and the upper extension 22 of the lever 2I moves in a slot 23 of the card stop 28. It is obvious that when thecontrol card I0 is positioned as shown in Fig. 5 it will engage the portion 22 of the card lever 2l thereby rocking the latter so as to close card lever contacts 24. In Fig. 5, the control card II) is shown in lts proper analyzing position and having operated the card lever 2l the contacts 24 will be closed. The card lever 2l is so positioned that when the control card is placed in the analyzing unit, with its printed face downward, the rearward right side corner of the control card will cooperate with the card lever 2| and actuate the same.

The movable analyzing unit is carried by a pair of parallel supportingframe plates 25, each of which is carried by the base I3. The movable contact unit comprises two U-shaped plates 26 and 21 which are joined at their ends by assembly screws 21a thereby providing a unitary frame structure. Interposed between bars 28 of insulating material are four contact plates 29 each of which is provided with a series of contact fingers 30. The ngers 30 are so positioned that they are adapted to pass through the perforations of the card I0 of the four lower horizontal rows of perforations and passing through such perforations make contact with the bars I8 which are positioned directly beneath thecontact lingers 38, as best shown in Fig. 3. A series of assembly bolts 3| are provided to assemble the bars 28, contact plates 29 and plates 26 and 21 so that the contact plates 29 may be supported and be carried by the frame comprising the U-shaped plates 26 and 21.

In order that the analyzing unit may be rocked downwardly from the normal position shown in Fig. 6 to the position shown in Fig. 5, and then slightly to the left so that the contact fingers 38 Awill make positive connection with the bars I8 through the perforations, the following means is provided and the description will be given in con- 5 nection with the arrangement shown in Fig. 5 since the construction is duplicated for both ends` of the movable analyzing unit. As best shown in Fig. 5, the side plate 32 of the U-shaped plate 26 carries rollers 33 and 34, the roll'ex` 34 co- 10 operating with an elongated slot 35 formed in the side plate 25 and the roller 33 cooperates with an elongatedv slot 36 which is elongated both inv Vertical and horizontal dimensions for a. reason to be subsequently apparent.

The side plates 25 form the bearings for a rock shaft 31 which at its midpoint is provided with an operating handle or lever 38. The rod 31 carries at each end a cam 39. With the parts in the normal position shown in Fig. 6 it is ob- 2 vious that by rocking the shaft 31 by the handle 38 in a clockwise direction, the cooperation of the cam 39 with an extension 48 of the plate 32 will cause the analyzing unit to be rocked about the axis of the roller 34 as a pivot. 'Ihis operation lis 25 effected because a spring 4I is extendedbetween a spring supporting pin 42 carried by the plate 25 and a spring supporting pin 43 carried by the side plate 32, the springs 4I at both ends being of sufficient strength to normally hold the analyz- 3o ing unit in the position shown in Fig. 6. The upward normal position of the analyzing unit with the contact fingers 30 out of cooperation with the control card I8 is effected by means of a spring 44 which extends between the spring supporting pin. 43 and a supplemental pin 45 also carried by the plate 25. The spring 44 is of suicient strength to hold the analyzing unit in the upward normal position shown in Fig. 6.

Therefore, as the shaft 31 is rocked clockwise 4 by the lever 38 the analyzing unit will be rocked until the roller 33 strikes the horizontal edge of` the slot 36. A further rocking of the shaft 31 by the lever 38 will cause a projection 46 of the cam 39 to be brought into engagement with the extremity of the extension 48 to laterally move the analyzing unit to the left, 'as viewed in Fig.

5, or in a forward direction in the machine,and

such movement will be eiected until the movable 5o analyzing unit is in the position shown in Fig. 5.

The rst tilting movement of the analyzing unit will cause the contact fingers 30 to pass through the perforations located at the junctions of the vertical card columns and the four lower 55 horizontal rows. The subsequent lateral movel ment of Lthe analyzing unit will cause the contact lingers to scrape over the contact bars I8 thereby making rm contact therewith and this operation is enabled due to the fact that the per- 90 forations are rectangular or oblong, .as is best shown-in Fig. 2.

Due to the tendency of the spring i4 te upwardly elevate the right end of the analyzing unit and the tendency of spring 4I to move the unit to 55 the right it will be seen that primarily on account of the weight of lever 38 which will overcome this combined action the extremity of the projection 46 will be maintained in locking cooperation with the extension 40 and thus maintain the analyzing I70 unit in the position shown in Fig. 4 so that continuous electrical contact may be maintained through the perforations of the control card, and such condition will be maintained until the han'-V dle 38 is reversely rocked to bring the movable 76 analyzing unit out of analyzing position to enable the insertion of the next control card I0.

CARD PUNCHING MACHINE The card punching machine, in which the present improvements are preferably incorporated, is Well known and fully shown and described in the patent to F. Lee and G. F. Daly, No. 1,976,618,

dated October 9, 1934, and only so much of the operation thereof will be explained as is necessary for an understanding of the operation in tion with the present invention.

There'will now be described, in a general way, the operation of the key controlled punching ma.- chine whereby such punching operations may be affected.

In general, referring to Fig. 10, the punching machine includes a card supply magazine 50, (see also Fig. 1) from which cards are fed singly from the bottom by means of a picker knife 48 (Fig. 1) of a well known form, and which, as described inl the aforementioned Patent No. 1,976,618, feeds the cards to a position beneath the series of card punches 5I with the first column of the card in position to receive the perforation. From this position, if manual punching operations are to be effected on the first and succeeding card columns as in the present example, a card is engaged by a pusher 52 (Fig. l0) mounted on an escapement Connecrack 53 which, under control of a conventionall escapement mechanism shown in the top of Fig. 8, permits the advance of a card step by step for successive card punching operations.

The escapement mechanism, shown in Fig. 8 and just referred to, is of the same general type as that disclosed in the patent to Schaaff, No. 1,426,223 dated August 15, 1922,` andthe aforementioned patent to Lee et al., No. 1,976,618 also gives a full description of the construction and operationof this escapement mechanism.

A series of keys 54, shown in Figs. 1 and 10, are adapted to select the punches for actuation, and the operation of each key, as is well known, will effect the shifting of an interposer 55 (Fig. 10) which rocks a bail 56 about its pivot 51, elevating link 58 to close contacts 95, and which latter contacts correspond to similarly designated contacts in Patent No. 1,976,618. This, as explained in the aforementioned patent, and by a circuit to be later described herein is adapted to cause the energization of a magnet 49 (corresponding to a similarly designated magnet in Patent No. 1,976,618) which, through its armature 6I and link and lbell crank connections 62, is adapted to draw downwardly a punch bar or plate 63 to force the selected interposer 55 against the related punch 5| thus perforating the card. The escapement mechanism thereby-operates to feed the card carriage a distance of a hole step of the card,

In general, after each card column is manually punched, the carriage escapes to the next card column position and this operation is repeated until the selectedcard field is completely punched in all of its card columns.

SKIN-ING or CARD FIELDS of cards and since they are already punched, time will be saved by omitting operations in such card fields by skipping operations of the nature just described.

One form of apparatus for effecting the skipping of selected card fields is fully shown and described in the patent to H. L. Read, No. 1,962,750 dated June 12, 1934,A and in view of the full disclosure of this form oi' mechanism only a general description will be given herein.' This mechanism includes a bar which is carried by the escapement .rack and which is provided with suitable notches and cam surfaces which through intermediate mechanism is adapted to elevate the stepping dog 65 (Fig. 8) to release the escapement rack and the card carriage. The card carriage will thereupon skip over the columns or fields which are not to be punched. The aforementioned skipping mechanism may be automatically effective upon the carriage reaching a predetermined column by manual punching operations, or alternatively, by the depression of the usual skip key which is the X (Fig. 1.) or 11 index point position key. As will be more fully described hereinafter, in contradistinction to the all-mechanical and manually controlled skipping mechanism shown in the patent to Read, No. 1,962,750 the present improvements incorporate a skipping mechanism which is under electrical control, and may be selected for operation under control of perforations in the horizontal card column No. 1, as disclosed in the control card l0 in Fig, 2.

DUPLICATING MEcHANrsM Machines of the type herein shown are provided, -as is the present machine, with a duplicating mechanism which is adapted to automatically duplicate from a master card M (Fig, '1) certain data thereon and punch a representation of this data in a selected card field. In the present machine, this function is automatically initiated, as will be subsequently described in connection with an example, under control of selected perforations in the horizontal row No.4of the control card IU, shown in Fig. 2. The duplicating mechanism is also old'and is fully shown in the patent to F. Lee et al., No. 1,976,618 and in view of the full disclosure in this patent only a general description will be given herein of this part of the mechanism.

The master card M, referring to Fig. 1, is placed in position between arms l0 attached to and extending ,from the escapement rack 53 so that the mastercard will advance step by step with the new card being prepared.

When a predetermined field of the master card M is correlated with the analyzing brushes B8 (see Fig. 9) the perforation at the vcard column which is to control duplication, and succeeding columns, will permit an electrical contact to be made between the related analyzing brush 68 and a contact roll 69 thereby causing the energization of an associated selector magnet 60.

Referring to Fig. 10, it will be noted that the energized selector magnets will attract their armatures and thereby rock arms 'll which have mechanical connections to the keys 54. Consequently, the energizaton of the selector magnet 60 will cause a punching operation in the same manner as if the related key 54 was depressed.

This duplicating mechanism is more fully described in the aforementioned patent to Lee et al., No. 1,976,618, and the reference numerals 60, 68 and 69 in Fig. 9 indicate elements similarly designated in the last mentioned patent.

COLUMN CUT OUT been accomplished by the opening of contacts |35 (see Fig. 9), and which contacts correspond to similarly designated contacts in Patent No.-

The prior construction for cutting out the duplicating action included a bar which is carried by the escapement rack and which was provided with low and high portions so as to cause the closing and opening of the contacts |35 when predetermined card fields come into operation. This prior art construction is fully shown in Figs. 12, 13 and 14 of the aforementioned patent to Lee et al., No. 1,976,618.

As will be more fully described as the specication progresses, the present machine includes a novel electrical control means whereby a similar function may be effected without requiring the use of the so-called high and low bar.

OPERATION oF THE MACHINE The general operation of the machine will now be explained in connection with a specific example to indicate the various steps involved in the punching of a card which requires the use of the four different functions previously described.

It should be understood that the present example is merely illustrative and that the operations for different cards may be varied in a'ccordance with the different requirements. 'Ihis is particularly true since the present control means are flexible in their selection which permits operations of the machine to be altered and varied in sequence in accordance with the dierent requirements. l

The control card shown in Fig. 2 illustrates one form of control in which the different functions of the machine may be carried out in the following manner:

Key punching operations Columns 1 to 11 Card carriage skipping .operation Columns 12 to 21 Key punching operations Columns 22 to 70 Cut out of the duplicator Columns 71 to 76 Duplication of data on master card Columns 76 to 80 The manner in which the functions of the machine are carried in the above sequence will now be described.

Referring to the circuit diagram (Fig. 9), when 'current is applied to the line wires |00 and I0|,

a circuit is made as follows: from the positive line side I 00 to contacts |36, which correspond to similarly designated contacts as shown in Fig. 1 of Patent No. 1,976,618, and also Fig. 10 herein, the circuit extending through such contacts since they are normally closed, to contacts |41, and which correspond to similarly designated contacts in Patent No. 1,962,750, by a wire |02 to a relay magnet 80, thence through card lever contacts 24 which are now closed since it is assumed that the 'control card is in analyzing position and the movable analyzing unit has been operated, and

4 and 5 and which has previously been referred Contacts |41 are retained closed to retain relay magnet energized but are opened after the carriage is located in the last card column, as explained in Patent No. 1,962,750.

As best shown in Figs. 1 and 3,'thearms 10 which carry the master card M also carry a plate |04 provided with ratchet teeth |05. 'I'he right end of the plate |04 carries insulated therefrom a bracket |06 (Figs. 3 and 5) which carries a pair of brushes |01 and |08. The brush |01 makes continuous contact with the common conducting bar I9 and the brush |08 makes successive contact wlth the ends of the bar I8, as will be clearly understood by reference to Fig. 5.

It was previously pointed out, and as is also shown in Fig. 9, noy bar I8 isprovided for the first column and when the card carriage is in the first card column punching position, the circuit usy from the negative line side to the brushes the circuit for punching operations extends from the positive line side |00, through contacts |36, through contacts 95 which are closed by any oi' the punch keys to the magnet 49, which is thereby energized to eiTect punching operations, and thence to the negative line side I0 Since the carriage which carries the card to be punched, and also the master card, are moved step by step, it is obvious that the contact brushes |01-|08 will make contact successively with the bars I8. When a punching operation is effected for the 11th column, the card carriage will, after a punching operation, escape to the 12th column. At this time a circuit connection will be made in the following described manner.

Since the 4related contact finger 30 of the contac-t plate 29 of the horizontal row No. 1 makes contact with the perforation at the 12th card column, the previously described circuit will be extended by the contact finger 30 and the contact bar I8 to a wire |31 (Fig. 9) and thence The armature |I3 of the magnet I I0 is pivotedl by a stud I|4 carried by the plate ||2. The

free end of the armature ||3 underlies the resilient contact blade I|5 of contacts ||6, the resiliency of the contact plate ||5 causing the free end of the armature to abut against an adjustable screw H1. 'I'he adjusting screw H'I is carried by a bracket ||8 which is carried by the plate H2.

A push rod I9 is slidable in the bracket plates H0 and H8 and the upper and lower portions of the push rod H9 are coupled together by a screw coupling member |20, the purpose of which is to decrease or increase the length of the push rod to effect a desired adjustment of the latter. The push rod H9 is mounted, therefore, for vertical operation and in the position shown in Fig. 8 which is the normal position, the coupling member |20 normally rests upon the free end of the armature H3. The upper extremity of the push rod H9 underlies a lug |2I which is an integral offset of the stepping dog or holding pawl 65, it being clear' that when the push rod ||9 is elevated the holding pawl 65 will be elevated so as to be disengaged from the teeth of the escapement rack 53 thereby permitting the carriage to be freely moved. i 0

When the contact bar |8 of column I2 card is engaged by brush |08 the magnet I 09 is energized as previously described, thereby attracting its armature H3 and closing contacts H6 at substantially the time the holding pawl 65 is disengaged from one of the teeth 'of the escapement rack 53. The card carriage carrying the card to be worked upon, as well as the master card, is thereby free to be moved under control of the usual spring operated drum employed in card punching'machines of this type. The means for moving .the card carriage by such spring operated means is well known and is fully shown and described in Fig. 17 of Patent No. 1,772,186, dated August 5, 1930.

From Fig. 8, it will be seen that the armature H3 is provided with a downwardly bent latching lug |22 and said lug normally engages the upper end of an armature |23 of a magnet |24. As best snown in this figure the normal latching of the armature |23 causes the closure of the contacts |38 which, it will be recalled, permit the energizatlon of the magnet |09. When the armature H3 is fully retracted, due to the complete energization of the magnet |09, the lug |22 will be fully disengaged from the upper extremity of the armature 23 causing a spring 23a to rock the armature |23 so that its upper end is beneath the lug |22. This will latch contacts H6 closed and also hold pawl 65 in disengaged position. The rocking of pawl 65 to disengaged position occurs substantially at the time contacts H6 closed and also the push rod H9 has elevated the holding pawl 65 to disengaging position. Therefore, contacts |38 are not opened to deenergize magnet |09 until the card carriage is unlatched, the magnet |09 is completely energized, and also contacts H6 are closed. The opening of the contacts |38 will thereby cause the deenergization of the magnet |09 permitting the arc due to the break of the circuit to be taken by contacts |38 instead of the contact bar I8 and brush |08.

The closure of contacts H6, as best shown in Fig. 9, will cause a circuit to be closed from the positive line side |00, contacts |36, to a wire |25, to a relay magnet 26, through the contacts H6 now closed, a Wire |21, to a wire |59, to the negative line side |0|, thereby causing the energization of the magnet |26 and the closure of relay contacts |26a.

The punch carriage will now escape freely until the perforation in the 22nd column of the.

second horizontal row is rendered effective which will, by means now to be disclosed, stop the operation of the skipping mechanism and condition the machine so that key punching operations or duplicating operations may be effected on column 22 and succeeding card columns.

The closure of relay contacts |26a. will effect a closure of a circuit which leads from the positive line side |00, through control contactsv |36 now closed, a wire |29 to the magnet |24, from said magnet to a stop-skip control magnet |30 through relay contacts |26a tothe contact plate 29 associated with the second horizontal row of the control card (see Fig. 2), the related contact bar |8 associated with the 22nd card column, the brush |08, brush |01, contact bar |9, wire |03, relaycontacts 80h, card lever contacts 24, duplicator cut-out contacts |35 to the negative line side |0I. Itis obvious, therefore, that the above mentioned circuit is closed to effect the energization of the magnets |24 and |30 when the card carriage has skipped to the 22nd card column. At this time, as will now be described, mechanism which causes the stopping of the card carriage at the 22nd card column position will now be effective. This mechanism is best shown in Fig. 3 at the left hand portion thereof.

A base plate '|39 is adapted to carry parts of the stop-skip mechanism and said base plate has attached thereto a bracket which carries the aforementioned magnet 30 and which may be termed a stop-skip control magnet. The armature |3| of the magnet |30 is pivoted on a stud |32 carried by the base plate |39. The armature |3| is provided with a downwardly extending carriage stop extension |33 and a spring |34 extended betw'een the extension |33 and the bracket |40 maintains the stop extension |33 against an adjusting screw |42. By means of the adjusting screw |42 the armature |3| is adjusted to its desired normal or attracted position.

As shown in Fig. 3, the stop extension |33 is adapted to cooperate with the ratchet shaped teeth |05 of the plate |04 and said stop extension should be maintained in such a normal position so that it is free of the ratchet teeth 06 to permit the free movement of the card carriage. The means for effecting this desired relationship comprises an adjusting .means now to be described in detail. The lbase plate |39 is attached to the plate H by means of a screw 43 and the base plate |39 may be pivotally adjusted about the screw |43 so as to effect the desired relationship between the stop extension |33 and the ratchet teeth |05. Carried by the plate is a square stud |44 which is riveted to the plate H, the stud |44 passing through a hole |45 in the base plate |39. An adjusting screw |46 is received by a square stud |48 which is riveted to the plate |39 and the adjusting screw is in engagement with the stud |44. By turning the adjusting screw |46, the plate |39 will revolve around the shoulder of the screw |43 and when the desired Vadjustment has been made the plate |39 may be securely fastened to the plate H by means of a pair of screws |49.

By means of the aforementioned two adjustments, the stop extension |33 is adjusted so that it is normally free of the ratchet teeth |05 so that when the armature |3| is attracted by the energization of the magnet |30, the stop extension |33 will engageone of the ratchet teeth 05 to thereby stop the movement of the card carriage. It is evident that by the above described mechanism, the card carriage will be positively stopped after it has escaped a distance of the predetermined columns.

In order to latch the amature 3| in its attracted or carriage stopping position, the following described means is provided: The armature |3| is provided with a depending portion which upon the attraction of the armature is received by a shoulder |5| of a. latch which is'formed as a bell crank pivoted on plate |39, and comprising an arm |52 which is provided with the shoulder |5I, and an arm |53 to which a spring |54 is secured. The spring |54 maintains the arm |53 against a collar |55 which is attached to an operating rod |56, and which in the position shown in Fig. 3 is prevented from moving to the right. It is obvious that when the armature |3| is attracted, the depending portion thereof will be caught by the shoulder |5| thereby latching the armature |3| in such position that the stop extension |33 will be maintained in locking relationship with one of the ratchet teeth |05 thereby positively holding the carriage in its stopped position and preventing its rebound.

From the wiring diagram (see Fig. 9), it will be noted that the magnet |24 is energized at the same time as magnet |30 because it is in electrical series connection therewith. However, the

magnet |30 operates faster than the magnet |24 so that the carriage will be stopped before the l complete energization of the magnet |24 has been eiected. After the card carriage has been stopped, the attraction of the armature |23 (see Fig. 8) of the magnet |24 will cause the upper end of the armature |23 to be withdrawn to theA left out of cooperation with the latching lug |22 thereby closing contacts |38 and causing said contacts to be relatched in closed position, as shown in Fig. 8.

The above described operation will, of course, permit the push rod ||9 to drop downwardly to cause the holding pawl 65 to reengage with the escapement rack 63 and, furthermore, permit contacts ||6 to open to deenergize the relay magnet |26 which opens its relay contacts |26a to cause the deenergization of magnets |24 and |30.

' However, the armature |3| of magnet |30 will remain in latched position.

It occasionally happens when certain fields are to be skipped and for such elds the master card M contains perforations in one or more columns to be skipped, that such duplicating operations should not be effected. From the wiring diagram shown in Fig. 9, it would be seen that the circuit from the elements of the duplicator which comprise magnet 60, brushes 68, common contact roll f69, extends through normally closed contacts 9|,

and also contacts |28. The contacts |28 .correspend to contacts shown in Fig. 11 ofthe Patent 1,976,618, dated October 9, 1934, which are designated by the same reference numeral. As more fully described in the last mentioned patent, contacts |28 are opened by the rocking of the pawl I4 manual punching operations -to punch the representation of data in column 22 and succeeding card columns, it being observed that the carriagel has been positively stopped at the 22nd card column position.

For punching in the 22nd card column position, on'e of the keys 54 (Fig. 10) is manually depressed to eiect a punching operation in the manner prevlously described. By the operation of one of the keys 54, contacts |95 (Figs. 9 and l0) are closed and such contacts correspond to similarly designated contacts in Fig. 2 of the patent to F. Lee et al., No. 1,976,618. The closure of the contacts |95 will effect the closure of the circuit from the positive line side |00, through contacts |36, through contacts |95 now closed, a resistance R, a magnet |58', which may be termeda release magnet, and a wire |59 to the negative line side |I, thereby causing the energization of the release magnet |58. The energization of the magnet |58 concurrent with a card-.punching operation, will attract its armature |59 (Fig. 3) and since the latter abuts the right end of push rod |56, the latter will be moved to the left. Since the collar |55 engages the arm |53, the bell crank which comprises the arm |53 and the arm |52 will be rocked counter-clockwise about its pivot thereby disengaging the shoulder from the armature |3|. Spring |34 is now eiective to rock the armature to bring the stop extension |33 out of engagement with the ratchet teeth |05 of the plate |04 thereby ,freeing the carriage so that its step by step movement may be placed under control of the regular escapement mechanism, shown at the top of Fig. 8.

It will be noted that the card carriage now escapes from the 22nd card column position to the 23rd card column position and the brush |08 is now disengaged from the bar I8 correlated with the 22nd card column position thereby opening at this point the circuit'which includes the relay contacts |26a. It should be noted, however, that the opening of the circuit at this point did not effect the deenergization of magnets |24 and |30 and which would result in arcing at the bar I8 and brush |00. This cannot happen because of the fact that when contacts ||6 (Figs. 8 and 9) were previously opened, the relay magnet |26 was deenergized to cause the opening of the relay contacts `|26a, and which caused the deenergization of the magnets |24 and |30. It will be seen, therefore, that the opening of ythe circuit to the magnets |24 and |30 is effected vby the previous opening of relay contacts |26a and these are o1' such dimension so as to withstand without deterioration the arcing due to the breaking of the circuit which includes these two magnets.` This operation is preferable -instead of breaking the circuit by the bars I8 and the brush |08.

Successive manually operated card punching operations may ensue until the carriage reaches the 71st card column position at which time another function will take place. Of course, if the card columns comprising card column 22 and ensuing card columns of the master card M contain perforations, it will be obvious that upon les which such cut out operations are performed will now be described in detail.

Upon effecting a punching operation in the th column, either by a manual punching operation or by an automatic duplicating operation, the card carriage is skipped to the 71st card column position and upon the brush |08 (Fig. 8) encountering the bar I8 correlated with the 71st card column, a circuit will' be closed which is described as follows. This circuit is from the negative line side |0|, through the duplicator cutout contacts |35 now closed, card lever contacts 24 now closed, relay contacts 80h now closed, wire |03, common current conducting bar |9, brush |01, brush |08, the bar |8 correlated with the 71st-column, a rela-ted contact finger 30, the contact plate. 29 of horizontal row No. 3, a wire |6|, contacts |62, magnet |63, contacts |36, to the positive line side |00. 'I'he closure of this circuit will effect the energization of the magnet 4|63 since contacts |62 are normally closed.

Referringnow to Fig. 7, it will be seen .that the energization of the magnet |63 will attract its arma-ture |64 so as to close contacts 92 and open contacts 9|. Contacts 92 will be latched in closed position by the engagement of a bent lug |64a with the lower extremity of an armature |66 of a magnet |65. The attraction of the armature |64 to latching position will also permit the opening of contacts |62, thereby opening the circuit to the magnet |63 and causing its deenergization, although the armature |64 thereof will remain in latched position, as well as the closure of contacts 92. The opening of the contacts |62 to effect the deenergization of the magnet |63 causes the arc, due to the breaking of circuit of magnet |63 to be taken by the contacts |62 instead of the brush |08 when the latter moves to the 72nd card column position, concomitant with a key controlled card punching operation in this column,

Referring now to the top of the wiring diagram in Fig. 9, it will be seen that the opening of contacts 9| open the circuit to the duplicator so that if there was a perforation in the 71st card column of the master card no duplicating operation would be effected for this column on the card to be operated upon. This, of course, is also true for succeeding card columns since contacts 9| remain in latched open position.

Since no duplicating operations will be effected, the card to be operated upon will be manually punched and the card carria-ge will escape step by step. When the card is punched in the 75th column, the regular escapement mechanism will permit the carriage to escape to the 76th card co1- umn and a circuit is closed which is described as follows: from the positive line side |00 to relay contacts |36, contacts |28, contacts 92, wire |61 to the magnet |65, a wire |68 to the contact plate 29 associated with the horizontal row No. 4, through a contact finger associated with the 76th card column, through the perforation at such card column of the control card |0 shown in Fig. 2, to the contact bar I8 related to the 76th card column, brush |08, brush |01, wire |03, relay contacts 80b, card lever contacts 24, duplicator cutout contacts |35 now closed, to the negative line side |0|. The aforementioned circuit will cause the energization of the magnet |65, and as shown in detail in Fig. '1, will attract its armature |66 thereby unlatching the armature |65 to permit the closure of contacts 9| and the opening of contacts 92. In this operation, the contacts |62 will again be closed to condition the circuit which includes the magnet |63 for subsequent closure. The closure ofv contacts 92 i will close the circuit to the duplicating brushes 68 and since it is assumed perforations are present in the master card M in columns 16 to 80, duplicating operations will be effected on the card to be punched for such card columns.

When the card carriage occupies the last card column position contacts |50 are closed and contacts |41 are opened and such contacts correspond to simillarly designated contacts shown in Figs. 7 and 13 of the patent to Read, No.

1,962,750 and which operation is fully explained therein.

The present machine is also provided with a card ejecting mechanism, designated by the reference numeral |69 in Fig. 1, and also a power driven carriage return and card feeding mechanism so that the carriage is returned and a new card is fedv to the carriage after the punched card has been ejected. These mechanisms are also well known in the art and are fully shown and described in the patents to Lee and Daly, No. 1,976,618; F. M. Carroll, No. 1,976,600 and H. L. Read, No. 1,962,750 and for this reason are only generally shown herein. The card ejecting mechanism shown in Fig, 1 is set in operation by the closure of contacts |50 which cause, by the circuit shown in Fig. 9, the energization of a magnet |99, and which magnet corresponds to a similarly designated element in Patent No. 1,976,618. As more fully described in the last mentioned patent, the energization of this magnet causes the operation of the card ejecting mechanism which, in turn, causes the closure of contacts 20| in the same manner as the similarly designated contacts disclosed in Pa-tent No. 1,976,618. The closure of the contacts 20| will effect the energization of the magnet |15, which also corresponds to a similarly designated magnet in Patent No. 1,976,618. The magnet |15 is also shown in Fig. 10 and upon its energization, it will attract its armature so as to cause the opening of contacts |36 and the closure of contacts |90. The closure of contacts will set a motor |51 into operation which will return the card carriage to its rst card column position, as well as the master card, and a-lso effect the operation of the card feeding mechanism so that a new card is fed to the card carriage.

'I'he above operation is briefly explained herein since it is well known in the art.

Fnzs'r COLUMN CONTROL SwrrcH In the illustrative machine when the card carriage is returned after a punching cycle the carriage will be returned and stopped in the first card column punching position, and when the card carriage is positioned at the first card column an insufficient time is available for causing both the restoration of those parts which were utilized in the performance of the last function on the preceding card operated upon and the setting of parts which initiate the initial -function on a succeeding card. It is preferable, therefore, in view of the limited time available to effect the restoration of such parts to provide mechanism acting before the card carriage is at the first card column position and which conditions all of the parts to normal so that such parts are available to function immediately at the time the carriage is at the first card column position. This is attained, in the preferred embodiment, by a so-called rst column control switch. This switch is shown in Fig. 1 and the numeral |10 and is positionable to four dier ent positions; namely, "skip, punch, duplicate, and cut-out." The switch arm |10 is also diagrammatically shown in Fig. 9 and comprises, as show in this figure, a switch arm |10 which may be selectively positioned in operative correlation with four contact points, which are identified by letters designating the function which is selected at the different positions of the switch arm |10. The switch arm |10 is normally in the position P" in which manual punching operations are to be effected for the first card field. In order to understand the function of the switching mechanism just referred to, several examples will be explained indicating how it cooperates with other parts of the machine so as to attain the desired mode of operation.

1. Las: card new skipped, followed by. manual punching of first card field of the next card It will be assumed that the last card ileld was to be skipped and that the first card field of the next card is to be manually punched.

Recalling the previous description, it will be observed that under control of a perforation in the horizontal row No. 1 of the control card I0 a circuit was closed, at the beginning of the card field to be skipped, to a magnet |09. From Fig. 8, it will be noted that the energization of magnet |09 caused the latching of contacts H6, and the closure of such contacts caused the energization of the relay magnet |26 and the closure of relay contacts |26a, and such relay contacts, due to the latching of contacts I6, are retained closed during the skipping of the carriage corresponding to the card field to be skipped. When the card carriage reaches the 80th card column position, or the last column position of the card carriage, contacts |41 are opened thereby opening the circuit to the relay magnet 80, since this circuit extends from the positive line side |00, contacts |36 now closed, contacts |41 now open, relay magnet 80, card lever contacts 24 now closed, and duplicator cut-out contacts |35, now closed. The deenergization of the magnet 80 will cause the closure of the relay contacts 80o when the card carriage is at the 80th card column position, and a circuit will now be closed; from the positive line side |00, through relay contacts |36, magnet |24, magnet |30, relay contacts |26a now closed, to the switch point designated P, switch arm |10, the relay contacts 80o, a wire |1| to card lever contacts 24, and duplicator .cutout contacts |35 to the negative line side |0I. It will be recalled that the energization of the magnet |30, referring to Fig. 3, will cause the stopping of the card carriage at the 80th .card column position. At the same time magnet |30 is energized, the magnet |24 is also energized so as to cause the opening of contacts ||6 which effects the deenergization of the relay magnet |26 and thus, the opening of contacts |26a to effect the deenergization of the magnet |30. However, it will be recalled that the stop extension |33 (Fig. 3) will be latched in such position so as to latch the carriage in the 80th card column position. However, in the operation of the machine now being described, the stop extension |33 is later unlatched due to the lfact that when the magnet 80 was deenergized at the 80th card column position a circuit was closed which is described as follows: from the positive line side |00, a wire |13, to relay contacts 80a, a wire |14, to the resistance R, the magnet |58, and thence by the wire |59 to the negative line side |0|. Magnet |58 is a larger magnet than magnet |80 and receives its .complete energization after magnet |30 is fully energized.

It is clear, therefore, that due to the above relationship the magnet |58 will be later effective to unlatch stop extension |33. When magnet |58 is completely energized it will rock bell- `crank |52-I53 to unlatching position, and at the Sametime the rod |56 will rock armature |3| and assisted by the spring |84 (Fig. 3) will cause the stop extension |33 to be moved out oi' the 80th card column position of the card carriage, and unlocking the latter so that it may be returned to the rst card column position.

It is noted that the above described operation is carried out at the80th card column position of the carriage thereby restoring all oi' the parts which were utilized in the skipping of the last card field to their normal positions and conditioning the machine so that initial card punching operations may be effected for the rst card field of the next card to be operated upon.

2. Manual punching of last card field, skipping of first card field of next card .y tion in which position the switchl arm is adjacent the contact point designated S in Fig. 9. Upon `punching the last card column, the positioning of the carriage to such card column position will open contacts |41, as previously described, to thereby effect the deenergization of' the relay magnet 80 causing the closure of relay contacts 80c, as previously described. A circuit will now be closed from the negative line side |0I, through card lever contacts 24, to relay contacts 80o, to the switch arm |10, the switch point designated S, and by the wire |31 to contacts |36, thence from such contacts to the magnet |09, to a' wire I0, and thence to contacts |36 now closed, to the positive line side 0|. This will effect the energization of the magnet |09, and, as will be recalled, will, by the controlling mechanism shown in Fig. 8, elevate the pawl and latch it in elevated` position. The card carriage is then .returned by power to the first card column position and when itis in such position, it will immediately be skipped to the extent of the card field which is to be skipped.

It is obvious, therefore, that if the first card ield is to be skipped the mechanism for. initiating this function will be set into operation when the last card column of the carriage has been reached.

. y 3. Cut-out of cluplicatm for last card field and duplicate for jirst card ,field of next card Another type of operation comprises the operation in which the cutout of the duplicator is effected for the last, card iield of a card and then duplicating operations for the first card field of the next card is to be effected.' In this type of alsV flatch contacts 9| in open position, and contacts 92 in closed position and such condition of the effect the energization of the magnet |65 thereby unlatching the armature |64 of magnet |63 permitting contacts 9| to close and opening contacts 92. l

It is obvious by the circuit connection just described that the closure of contacts 9| will render the duplicating mechanism operative for the first card eld of the succeeding card to be operated upon.

. 4. Punching of last card field, cut-out of duplicatofr for first card field of next card Another form of operation would be punching the last card field, either under control of the keys or by a duplicating operation, and then causing for the first card field of a succeeding card the cut-out of the duplicating operations under control of the first card field of the master card M. Since the first card field operation is to be a cut-out operation, the switch |10 is positioned so that it is adjacent the designation Cutout, Fig. 1, and in such position the switch arm |10 will be adjacent the switch point designated CU in Fig. 9.

As previously described, the circuit will be extended from the switch arm |10 to the last mentioned switch point, and thence by a wire |6| to contacts |62, thence to a magnet |63, then to contacts |36, and to the positive line side |00. This will cause the energization of the magnet |63 thereby latchng contacts 92 in closed position and contacts 9| in open position. This will set the controlling parts for the cut-out mechanismso that the duplicating operations for the first card field will be cut-out, thereby permitting manual punching operations for the first card field of the next card to be operated upon.

DISABLING F CARD ANALYzER DURING RETURN or' CARRIAGE When the card carriage is restored from the 80th card column position to the first card column position, the brushes |01 and |08 will, of course, also make contact with the respective bar I9 and the contact bars |8 in succession, thereby attempting under control of the perforations in the control card to effect the energization of the controlling magnets. However, fraudulent circuit closing is prevented during the return of the card carriage to the first card column position by the opening of contacts |36 and such contacts remain open until the first card column position of the carriage is reached. The manner in which the contacts |36 are retained open is fully shown and described in the aforementioned patent to Lee, No. 1,976,618, and also in Fig. 10 herein. The intermediate blade of the contacts |36 and |90 carries a block |86 of insulating material which is caught by a shoulder of a bell crank |01 when the armature is energized to close contacts |90 and open contacts |36. By means of the latching bell crank the contacts |36 are rf;-

tained open until said bell, crank is actuated by of contacts |36 and the opening of contacts |90 when the card carriage is at the first card column position.
